FRAME FOR HOLDING A BAG Filed Dec. 8, 1964 xA Y United States Patent3,313,504 FRAME FOR HOLDING A BAG Sven Thorlrild Stoltze, Rorsangervej,Denmark, assignor to A/S Extrusion, Copenhagen, Denmark Filed Dec. 8,1964, Ser. No. 416,713 Claims priority, application Denmark, Feb. 27,1964, 962/ 64 4 Claims. (Cl. 24899) The invention relates to a frame forkeeping a bag, more particularly a refuse bag of plastic foil insuspended or standing position with its mouth open, the said frame beingof the kind having a ring-shaped or frame-shaped holder member above forthe upper open part of the bag and a supporting member below to supportthe lower closed part of the bag.

It is an object of the present invention to provide such a frame whichis suitable for household use, for example, for being mounted on theinner side of the doors of kitchen cupboards, either for bags to bedisposed of through rubbish chutes or for refuse bags in general. Theinvention is also concerned with larger frames, for example to be placedon kitchen fioors or in other rooms, and another object of the inventionis to adapt such a frame in such manner that it is easy to Operate, moreparticularly in regard to exchange of bags, that is, removal of thefilled bag and attachment of an empty bag as well as storing of newbags.

An essential feature of the frame according to the invention is that afreely rotatable magazine roller is arranged in the frame, the rollercomprising a web consisting of a plurality of bags separated from eachother by means of transverse seams and a perforation or tearing lineparallel therewith, the frame having such an opening that the web ofbags may be pulled from the magazine roller up through the frame.

In such a frame a comparatively large number of bags forming acontinuous Web is kept in readiness on a magazine roller in the frameitself, and the bag in use at any particular time forms part of themagazine Web and is exchanged by the filled bag removed from the holdermember and lifted from the frame, whereby the succeeding bag of themagazine roller is pulled up into the place of the removed bag,simultaneously with a certain length of the web being unrolled and thefilled bag subsequently torn off the web and the mouth edge of the newbag attached to the holder member.

The easy and prompt exchange of bags may be subject to be counteractedby a difficult operation of attachment to the holder member, and theinvention is therefore also concerned with a very simple, yet effectiveattachment device. The essential feature of the said attachment deviceis that the holder member consists of an open ring or frame of bars madeof resilient material and so formed and placed in a substantiallyhorizontal plane that the upper edge section of the bag may be turnedinside out over the ring or frame and passed down around the frame,whereby the bag is retained by the resilient action of the ring.

As a result, the mouth section of the bag may be attached to the holdermember in simplest possible manner, its attachment being simply effectedby passing the bag into a position high enough for the bottom seam to bebrought to rest on the supporting member, after which the edge sectionprojecting above the holder member is turned down over the ring or theframe while the same is being slightly compressed, and owing to theresilience of the frame the bag will then be kept distended above andthe mouth edge prevented from sliding down.

An embodiment of a frame in accordance with the invention will now bedescribed with reference to the drawing, which shows a perspective viewof the frame.

3,3135% Patented Apr. 11, 1967 The frame consists of a wire latticework, each Wire of which is preferably covered by a plastic layer. Bymeans of two parallel horizontal frames 1 and 2 arranged below andconnected with each other by vertical stiffeners 3 there is formed abasket, the rectangular horizontal bottom of which consists of bentextensions 4 of the stiffeners 3. The inner ends of the said extensions4 are spaced apart at such a distance as to form a longitudinal slot atthe bottom of the basket.

Some of the stilfeners 3 are extended vertically upwards to formsupports 5 the upper ends of which carry a horizontal frame 6 having anopening 7 so that it may be compressed and rebound outwardly.

To the basket there is furthermore attached a rearwardly incliningbow-shaped part 8 of the lower end of which forms a horizontal bar 9which together with another horizontal bar 10 limits the said slot, thebars 9 and 10 being welded to the bars 4.

Two of the supports 5 are extended downwardly to form bows 11 whichconstitute a bearing for a magazine roller 12 on which is rolled a web13 consisting of a plurality of bags of plastic foil separated from eachother by means of transverse welding seams and a perforation line ortearing line 14 parallel therewith. The

' web of plastic foil is passed up through the said slot between thebars 9 and 10 and up through the frame 6 as indicated by dot-dashedlines and the upper edge portion 15 of the bag is turned inside outaround the frame 6 and down around the frame as illustrated. When thebag is being mounted, the frame 6 is compressed, and when the frame isreleased it rebounds thus retaining the bag rigidly distended at itsupper end.

At the upper end of the frame is attached a transverse bar 16 havingeyes 17 by means of which the frame may be screwed on to a verticalwall, for example the inner side of the door of a kitchen cupboard. Theframe may, however, also be formed with other means of suspension orsupport so that it may stand on the floor, for example.

When a bag is to be arranged ready for use in the frame, the web ofplastic foil is pulled up through the slot provided in the bottom of theframe, after which a corresponding length of web from the magazineroller is unrolled. The front part of the web, corresponding to thefirst bag, is passed up through the frame 6 to such height that thewelding seam which represents the bottom of the bag and which is locateddirectly above the perforation 14 is opposite the bars 4 whichconstitute the bottom of the frame or supporting member for the bag,after which the edge section 15 is turned inside out down over the frameas indicated by the dot-dash lines. The frame is now ready for use andthe bag may be filled with refuse. When the bag is full and is to bereplaced, the edge section 15 is removed from the frame 6 and is turneddown over the contents of the bag, after which the bag is pulled up fromthe frame, that is, to such level that the perforation and tearing line14 is located above the frame 6. The web of plastic foil is then tornoff along the line 14 so that the filled bag is separated from the web,and the filled bag may then be disposed of whereas the edge section 15as previously described is turned down over the frame 6, and the nextbag of the row of bags is ready for use.

The magazine roller 12 may be supported in other suitable ways, forexample in a tubular or trough shaped container at the bottom of theframe in which the roller may rotate freely when the row of bags ispulled upwards. The magazine roller may be arranged in any suitablemanner so that the row of bags may be pulled upwards as the bags areused.

The upper part of the bags may also be arranged and fastened in anydesired manner to the upper part of the frame.
